best paint or mark the cables, there are 4 ways to have them connected incorrectly.Sounds is very clear, just like higher end but not bass heavy or muffled.for $10-12, this can't be a wrong pair, yet stylishOkay I didn’t think I’d be writing a review about this… but these beauties cost 1/4 of what I paid for my Westone AM Pro30’s and sound INFINITELY better. I’m not kidding when I say this. I’ll be honest: this was my first time ever purchasing a product from KZ. I was super skeptical and honestly had the lowest of expectations considering this brand has always been viewed as a the budget friendly option. Well let me tell you… the sound these IEM’s produce is way above “budget” or average! The midrange is so full, not muddy at all and tons of definition and detail. The bass? Absolutely insane. You don’t have to search for low end with AST’s. These produce more low end a pair of 5” JBL studio monitors I have on my desk. Super punchy and clear and neither overwhelming or underwhelming. It’s EQ’d and sits perfectly in the mix for all genres.The only nitpick I have with these is that they could’ve polished the top end a little more. The highs leave a bit to be desired and sometimes instruments like cymbals sound like they’re being too controlled or tamed. But on the contrary, too many headphones and IEM’s I’ve used in the past have over-accentuated the high frequencies, creating for a very sibilant and harsh sound signature. With these IEM’s that’s a trade off I’m willing to accept for basically every other checkbox these tick off. But you can easily apply some minor EQ tweaks to get the highs you want/desire. Other than that, there’s simply no reason for a pair of in ears at this price point to sound THIS good! These are gonna be a sleeper for sure.Also, I’ll just warn you now… might as well look for a solid cable upgrade/replacement if you plan to purchase these. The included cable isn’t the best quality and there’s no cinch present to tighten the cable up alongside your back.I've used various pro studio phones and recently hifiman planar phones and bought these for under $30 for general use and as a pair with a mic for phone calls. For the price they sound terrific & friends say the mic sounds good on their end. The individual wire wraps over the back of each ear keep the earpiece in place. They allow sounds around you to pass through so you can hear the doorbell. They have very good mids & highs like a planar or electrostatic speaker. For $30 I have no complaints.I record multiple podcasts per week and these are so much more comfortable than the ear muffs I’d been using. The sound quality is great as well.These earphones work well. They are comfortable and easy to use.for the price whats not there to love its affordable and sounds amazing.I’m using these for my tv remote when I’m watching programs and everyone else is in bed. The clarity is truly awesome. I really need hearing aids but these are great now and will be great when I have to charge hearing aids. I love these! They will not disappoint.I've used various KZ earbuds and have spent hundreds of dollars on headphones before. When I snagged these, they were $17 with the mic. For the price, and given the fact these are still earbuds, they impress me daily. The electrostatic driver is QUICK and the magnetic drivers provide an overall good sound experience with pretty good tuning out of the box.I do prefer to equalize and tune it myself for a better sound curve, but I cannot complain at all. Treble is crisp, little details stand out, mid-range is not subdued, bass is powerful, vocals are sharp, and just the overall definition and clarity you receive from these earbuds make them worth far more than the price they're actually asking for.Comprados en mi caso con cupón promocional por 18 euros (o si fuera a precios similares), me parecen una opción bastante recomendable siempre que te vengan bien los tips o almohadillas que traen, ( no es mi caso, y a mí no me parece que sellen nada bien) o sino cambiarlas por otras que te sellen correctamente.Si en cualquier auricular in ear el sellado es fundamental en éstos que no son precisamente bassheads el sonido pierde cuerpo y se van a agudos si no sellan perfectamente.Traen unas almohadillas de silicona algo cortas y más cuadradas que las típicas de tipo seta y que en mi oído no sellaban nada bien. Con las que trae pero en talla grande, un poco mejor pero no suficiente y al final solucionado con unas corrientes que tenía por ahí de descarte, en talla grande.Respecto al sonido, primero decir que después de desechar siempre auriculares si no tenían buena pegada en graves, ( la típica firma en V ), me voy convenciendo de que unos graves con mucha pegada, aunque sean de calidad, siempre te retraen en medios y te quitan algo de detalle y excepto para tipos de música determinada como eletrónica o tal, voy prefiriendo unos graves más controlados y que no tapen tanto.Dicho esto y teniendo en cuenta que sí o sí necesitan un buen sellado, estos auriculares por menos de 20 euros me han parecido bastante cómodos, fáciles de mover, con unos graves controlados que no tienden a destacar, y unos medios-agudos que aunque en ocasiones se me hacen algo dominantes y me hacen bajar un poco el volumen, ofrecen a cambio un buen nivel de detalle y que no son para nada aburridos, siguen siendo disfrutones aunque no sean extra bass ... ...Für mich waren die Kopfhörer auch mit den anderen Gummis ungemütlich zu tragen und haben sich leicht bewegt. Der Klang ist okay. Bass ist kaum vorhanden da sie bei mir nie dicht abgeschlossen haben.Habe sie nur einen Tag benutzt und seitdem nurnoch als Ersatz gelagert.Für Sport funktioneren sie wahrscheinlich aber es gibt sicher bessere für ein paar Euro mehrIch benutze diese In- Ear Kopfhörer sowohl im Studio als auch bei Live Auftritte. Die Verarbeitung ist Super, Klang ist auch sehr gut und deutlich. Sitzt auch sehr gut am Ohr, wackelt nicht und stört auch nicht. Da habe ich ganz andere probiert ... Für diese Preisklasse klare Kaufempfehlung meinerseits!Also was die Lautstärke an geht… sehr laut!Leider ist der Kabel etwas kurz und es gibt leichtes Rauschen wenn kein Ton angespielt wird!Sonnst passen die Kopfhörer!Gute Tonqualität. Leider passen die Lautsprecher nicht gut in die Ohrmuscheln, so daß die Stöpsel nicht wirklich im Ohr bleiben. Daher wertvoller Hörverlust.
